Pavlovia not reading file name from resource properly

URL of experiment:

Description of the problem: on one of my image components i get the following error message

as you can see its missing the file ending, this is strange because in the spreadsheet that the file name is drawn from it is written with the correct file ending: .png

this happens with all items from that list, but not with a previous image component that uses a different list. all images are included in the additional resource tab in builder and all of the components were made in builder with just a tiny bit of js code for counterbalancing. When running the study local there is no issue and the images are depicted normally

i checked spelling, / etc. and also reuploaded all files including the images and lists, i hope i am missing something and would be happy about some advice

Make sure it’s using the correct excel file, and maybe try clearing the experiment’s cache on the server by switching it to ‘inactive’ and then back to ‘piloting’ or ‘running’. Basically it’s reading the information from the wrong place or an old version of the file, because it should have no way to cut off the file ending on its own.
